Chrome Extension Publisher Profile Scraper

This Actor builds one business-facing publisher profile from public Chrome Web Store publisher pages or extension listings. It prefers the stable publisher ID/profile URL when the listing exposes one, and keeps the evidence from every inspected extension in an explicit portfolio. extensionCount and the portfolio arrays describe the records actually collected under the request limits, not a guarantee of the publisher's entire catalog.

Each profile is expanded with publisher identity and stable profile identifiers, D-U-N-S where shown, public contact points, public address components, trader status, publisher and policy/support links, source listing identity, extension count, extension IDs, user/rating aggregates, latest version/update, most popular extension, categories, languages, featured count, portfolio policy/support URLs, and rich nested extension summaries. Each nested summary carries full formatted description text and sanitized HTML, category, ratings, users, version/update precision, website, privacy/support links, features, size, languages, media, structured related-extension cards, and version history. totalUserCount is the sum of collected listing counts, not a distinct-person count; averageRating is the unweighted mean of listing ratings, and weightedAverageRating weights them by their source review counts. Unknown trader/reputation values remain null when they are not explicit in the source.

Inputs

Use extensionId or extensionIds for known extensions, or provide official Chrome Web Store publisher-profile, detail, search, or category URLs through startUrls, sourceUrls, or urls. For discovery, use queries, query, or searchQuery with optional category paths. maxItems, maxRequests, and maxDetailRequests limit the profiles and pages collected. Set fetchPublisherProfile to true to follow the public publisher-profile link from a listing and collect additional extension cards; it is off by default.

Only public Chrome Web Store pages are in scope. The Actor does not sign in, solve CAPTCHA challenges, use private publisher pages, or infer a publisher identity that is not shown on the source listing. Search and publisher pages may expose a “Load more” control; this Actor reads the entries visible on the requested page, so the collected profile may not include a publisher’s complete catalog.

Output

Each dataset row represents a publisher and includes its public profile identifiers, contacts, listing links, and portfolio statistics. extensions and topExtensions contain the extension details available from the collected public listings. Counts describe only the extensions found within the selected limits; they are not a claim about the publisher's complete catalog.

The dataset and run summary are available in the Output tab. You can download dataset records in formats such as JSON, HTML, CSV, or Excel.

Example publisher record:

{
  "publisherKey": "example-labs",
  "publisherName": "Example Labs",
  "extensionCount": 1,
  "extensionIds": ["aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"],
